Just got back bfrom dealership the service advisor looked at the rear assist handles lined them up and pushed till they snapped obviously the factory forgot, I also had the tires rebalanced, the steering wheel shook violently from 65 to 80 on most roads, they replaced 1 tire, I had a similar problem on my 2012 and finally I had the uconnect upgraded to 3.19.0 the unit seems more responsive then before,I also talked too several mechanics you all need to keep a check on any oil leaks on the hemi it seems there is a filter issue which could include brand new vehicles and those that have had their vehicles serviced :lol::lol::lol::lol:
